FedEx told Business Insider on Tuesday that "the NRA uses UPS and not FedEx" for shipping from its online store.

The UPS jab was part of a statement from FedEx intending to "provide important, clarifying facts." The NRA's online store confirms that it uses both the US Postal Service and UPS to ship products.

"First, the pricing program that is the focus of these concerns is not for the NRA itself — it is for American small businesses and consumers that are members of the association," the latest FedEx statement says.

"FedEx has never provided any donation or sponsorship to the NRA, which is one of hundreds of alliance and association participants that serve more than one million customers," the company said in a statement on Tuesday. "FedEx remains committed to all our customers and the pricing we provide them independent of their political affiliations and views."
